In the five years the Steelers have played in the Super Bowl, the Standard & Poor's 500 has advanced an average of 22 percent annually, more than double the 8.6 average annual gain the index has racked up since the game was first played in 1967.

While the Steelers lost in their most recent Super Bowl appearance, the market has never had a losing year when the Steelers appear in the game. The S&P's worst performance for a Steelers year was 1979, when it advanced 12.3 percent after the Steelers beat the Cowboys in Super Bowl XIII, 35-31.
